* feat(agent): add GitHub Copilot CLI backend

Integrate Copilot CLI as a new agent backend using the stable
`-p` JSONL mode (`--output-format json`), following the same
spawn-CLI-scan-JSONL pattern established by claude.go.

Backend (server/pkg/agent/copilot.go):
- Spawn `copilot -p <prompt> --output-format json --allow-all-tools --no-ask-user`
- Parse streaming JSONL events (system/assistant/user/result/log)
- Extract session ID for resume support (`--resume <id>`)
- Accumulate per-model token usage for billing
- Filter blocked args to prevent protocol-critical flag overrides

Daemon config:
- Probe MULTICA_COPILOT_PATH / MULTICA_COPILOT_MODEL env vars
- Copilot uses AGENTS.md (native discovery) and default skills path

Frontend:
- Add Copilot logo SVG and provider switch case

Tests: 14 unit tests covering arg building, event parsing, usage
accumulation, and edge cases. All Go + TS checks pass.

* fix(daemon): add restart subcommand, make daemon uses it

- `daemon start` keeps original behavior: errors if already running
- `daemon restart` stops existing daemon then starts fresh
- `make daemon` now runs `daemon restart --profile local`

* fix(copilot): address review nits 1-5

- Nit 1: Add MinVersions["copilot"] = "1.0.0"
- Nit 2: Seed activeModel from session.start.data.selectedModel (falls
  back to opts.Model, then "copilot"). First-turn tokens now get correct
  model attribution.
- Nit 3: Handle assistant.reasoning/reasoning_delta → MessageThinking,
  reasoningText in assistant.message → MessageThinking,
  session.warning → MessageLog{warn}
- Nit 4: Extract handleCopilotEvent() method shared by production and
  tests — no more duplicated switch body that can drift
- Nit 5: Deltas write to output buffer as defense-in-depth; if process
  dies before assistant.message, output is non-empty
